And describe how to troubleshoot common issues related to lot and pack calibrations. You will be able to print a PDF copy of this job aid to refer to by selecting the resources link at the top right corner. Reagent calibration should be performed for a variety of reasons, including when a new reagent lot is loaded onto the system and when the calibration interval expires. The Italicus solution manages reagent calibration by using both lot calibrations and pack calibrations. The instructions for use contains the frequency requirements for lot and pack calibrations for each assay. The following slides will discuss the difference between lot and pack calibrations. Let's discuss the differences between lot calibration intervals and pack calibration intervals. First, it is important to recognize that a reagent pack aging on the shelf is not the same as one aging on the system. The stability of a reagent that is on the shelf is longer than one that is on board the system. Said slightly differently, a reagent shelf life is longer than its obes. Also, the shelf life of reagents applied to the entire lot, whereas obsi is based on individual packs. This phenomenon of shelf life and on board stability gives rise to the idea of lot or pack well calibration. Generally lot calibration intervals are longer than packed calibration intervals. Also, lot calibration applies to the entire lot, whereas the pack well calibrations apply to a single pack or well. The lot calibration interval starts when a reagent pack with a new lot is calibrated within 24 hours after it is loaded on the system. For the IM analyzer or 24 hours after the well is pierced by the Ch analyzer. The lot calibration will be valid for any pack within the same lot that is loaded on the system until the lot calibration interval expires. A reagent pack that uses a lot calibration to calculate results for the duration of the pack calibration interval orlon expiration, whichever comes first. The pack calibration interval actually applies to both reagent packs and wells within reagent packs. On the system there are two wells. In each reagent pack which are treated as separate reagents by the system. So on the analyzer, a pack calibration is actually a well calibration. The pack or well calibration interval is valid for an individual pack for the IM analyzer or well for the analyzer and not used for subsequent packs placed on the system. This is useful for labs that perform a low volume of tests because they can avoid disposing of reagent packs due to QC shifts seen when calibrating aged packs. In this slide we will look closer at the impact of using lot and pack calibrations. In the case of high volume assays, the system that is performing a large amount of tests for an assay uses the entire contents of the first pack for the IM analyzer or well for the analyzer of a lot before the pack calibration interval expires. When the first pack or well is replaced with a second pack or well of the same lot, the system uses the original lot calibration established by the 1st reagent pack or well to calculate test results. Subsequent packs or wells of the same lot do not require calibration when loaded or pierced until the lot calibration interval expires. High volume assays use lot calibrations, which leads to fewer calibrations for the life of a lot of reagents. In the case of low volume assays, the system that is performing a smaller amount of tests for an assay does not use the entire contents for the first pack or well of a lot before the pack calibration interval expires. Recalibration is required to ensure continued use of the pack or well on the system. The system uses the pack calibration to calculate patient results. Low volume assays use pack or well calibrations which lead to more stable QC results as reagents age on the system. Now let's look at a simple example. In this example, the lot calibration interval is 180 days and the pack calibration interval is 9 days. If you load a new pack with a new lot and calibrate within 24 hours after it is loaded, this will be the lot calibration. In the case of high volume assays, the lab is running through reagent quickly. If they are loading new packs with the same lot at least every nine days, they do not need to calibrate the new pack or well, because the lot calibration does not expire until day 180. The lab would only need to re calibrate every 180 days. In the case of low volume assays, nine days after the start of using the lot calibration, if the Packer well is still being used and needs to be re calibrated because the Packer well calibration interval has now expired, the calibration is a pack or well calibration. If the pack remains on board, it will have to be re calibrated every nine days until it reaches the onboard stability. In summary, you don't need to calibrate until you load a new lot. A pack is in use for more than nine days, or the lot calibration interval expires at 180 days. Now let's look at some real life examples. Following the first example, in this case study, we have an assay that has a lot calibration interval of 180 days and a pack calibration interval of nine days. The lab loaded a new reagent pack with a new lot and performed a lot calibration. Question one. What a calibration need to be performed if the reagent in well one was used within 8 days? No, because the nine day pack calibration interval has not yet been reached. Question 2. What a calibration need to be performed if the reagent and well one was not completely used up after 9 days. Yes, a pack calibration would be performed because the pack calibration interval has now expired. Question 3. Which calibration would be used if a calibration was performed after the 9th day? Upack calibration. Question 4. The reagent on board stability and well one is now expired. Which calibration would be used when, well, two is pierced? When well to his pierced, it would inherit the existing lot calibration which was performed on day one. Now for our next case study cholesterol another chemistry assay with two wells in each pack. The lab supervisor notices some imprecision in the QC data for an assay. To troubleshoot the imprecision they look at when calibrations have been performed. On day one, a lot calibration was created. Following this, the QC data was within range, but not right on the mean. Question one. At day 7A, pack calibration is performed on the same pack. Following this, how does the QC data look? The QC data is now on the mean. Question 2. At day 12A, new pack is loaded. What type of calibration would be used for the new pack? The existing lot calibration that was created on day one. Question 3. How does the QC data look following day 12? The QC data is within range but not right on the mean. Seven days later, on Day 19, the pack calibration interval expires. For the second pack. So a pack calibration is performed and the QC is back to the mean. Question 4. What could be causing the imprecision in the QC mean? Imprecision can be caused by different calibrations being active. In this example, the CALIBRATER'S used for the initial lot calibration were not fresh. When troubleshooting that in precision, it is important to be aware if you are looking at a pack calibration or lot calibration. Our last example involves the replacement of the source lamp on the Ch analyzer. Question one. What must be done after replacing the source lamp? Refer to online help. Wait one hour after replacing the lab perform Ch auto check after auto check completes, perform QC. Question 2. What must be done if QC is out of range post lab change? Perform a calibration to address QC. Question 3. What is the most likely calibration that will be performed? Pack calibration or lot calibration? Pack calibration chances are the reagent has been on the system for longer than 24 hours. Question 4. What happens when a new well is pierced after the pack calibration was performed? The system will revert to the lot calibration that was performed before the replacement of the lamp. Question 5. How can this pack calibration issue be solved? Load fresh reagent and perform a lot calibration or inactivate a well and perform a lot calibration on well too. This example applies to any parts that are changed for assay troubleshooting, IE probes, mixer, reaction or dilution, Q vets, etc.
